```
settings_ui: Fix scrollbar breaking when UI font size changes (#45099)

When the UI font size changes, the settings window's scrollbar would
break because list item measurements were cached and not invalidated.

We're using `ListState.measure_all()` to pre-measure all items for an
accurate scrollbar. When font size changes, these cached measurements
become stale but weren't being refreshed.

This commit fixes the issue by calling `ListState.measure_all()` when
settings change, ensuring items are re-measured on the next layout
without affecting scroll position.

Closes #43683

Release Notes:

- Fixed bug where changing the UI Font Size in the Settings UI would
break the scrollbar for the "Appearance" page
